We divide 20991872 by 320
Our goal is to divide 20991872 by 320.

Let's proceed to step 1:
If we divide 2 by 320, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 320

Advancing to step 2:
When dividing 20 by 320, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 320

Moving on to step 3:
If we divide 209 by 320, we get 0 and a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (9) of the dividend behind the 209 and repeat the process: 2099 / 320

On to step 4:
320 goes into 2099 6 times with a remainder of 179.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 1920 from 2099 leaves us with 179.
Grab the next digit (1) from the dividend, add it to 179, then carry on: 1791 / 320

Going ahead to step 5:
320 can be fit into 1791 5 times, resulting in a remainder of 191.
Write down 5 as next digit of the result. 
Result so far: 65.0
The remainder is 191 after subtracting 1600 from 1791.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 320

Going ahead to step 6:
1918 divided by 320 is 5 with a remainder of 318.
Put 5 as the next digit of the answer. 
Result so far: 655.0
Subtract 1600 from 1918 to get 318.
Grab the next digit (7) from the dividend, add it to 318, then carry on: 3187 / 320

Step 7:
The number 320 fits into 3187 9 times, leaving a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 6559.0
If we subtract 2880 from 3187, we get 307.
Append the next digit (2) from the dividend to 307 and continue with: 3072 / 320

Going ahead to step 8:
320 can be fit into 3072 9 times, resulting in a remainder of 192.
The next digit of our result is 9. 
Result so far: 65599.0
If we subtract 2880 from 3072, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
320 can be fit into 1920 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 65599.6
Subtract 1920 from 1920 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 320, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65599.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65599.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 65599.6 and a remainder of 0.0.
